I was just going to mention that. Although the quill is a 21.1 the external fork diameter is a 1".
And yes, some of the parts are BMX style.
You should also check the front mech as I've come across a few Raleighs that have an unusual seattube diameter. I remember trying to find an upgrade f mech for my Mustang bitd and the clamp size was 30mm iIrc.
